more than 70 people, including a dozen children, have been killed in a fire injohannesburg. it's thought a locked gate prevented victims escaping. the death of ten—year old sara sharif — police in pakistan say a formal request to investigate came five days after her body was discovered. commentator: fantastic, | what a win for katie boulter. and on an action—packed day at the us open, katie boulter leads the british charge. on bbc london — police chiefs will get new powers to sack officers. and campaigners say delays at a vital women's health service is leaving them in agony. good evening.

more than 150 schools in england have been told by the government that they must shut buildings immediately because they have been built using a type of concrete that is prone to collapse. children will now have to be relocated out of buildings containing the lightweight "aerated" concrete, and into other spaces, until safety work is carried out. in total, 156 schools have been confirmed so far as having problems. of those, 104 have been told they need to take immediate action, and the other 52 have already put measures in place to ensure pupil safety. the news comes days before the new school year begins. a list of affected schools is not being published though councils are being told of those in their area and it is up to the schools to inform parents. here's our education editor branwenjeffreys reports. yellow temporary classrooms in bradford. the stairs being craned

into place today. an emergency measure just days before term starts. part of the building closed for fear of a sudden collapse. parents like shazad absorbing the news. we heard about the school basically, right. there's some issues with the concrete side of things in certain parts of the building, which have been shut down. the head teacherjust sent a letter out. you could tell from the letter how emotionally stressed out she was because it's going to widely affect a lot of children. it is one of two schools in the city told they cannot fully open. around england, other schools have already closed buildings. more than 100 more have now been told to act. 104 of them we've assigned a case worker to each one of them, we're in touch with the school, we'll be sending surveyors in to look specifically and then we'll look to mitigate and minimise any impact that that has on children going back to school and obviously on parents. the department is in chaos and disarray and, you know, i've been raising this now

for months, the government have known for years that there was a need for action. they should come clean to parents, publish the full list of all of the schools affected and just get on with it. so what is reinforced autoclaved aerated concrete, or raac? it's lightweight, bubbly concrete used widely from the 1950s to 1990s. usually in roofs, sometimes in walls and floors. it is weaker than traditional concrete and it's past its life span. in essex, this school closed injune. the roof is made from raac. concerns were raised in 2018 when a roof collapsed elsewhere. so, why wait until now to tell schools to act? to school leaders and teachers preparing to start the new year next week in most cases, for children expected to come back to school, it feels incredibly last—minute, it feels rather shambolic if i'm honest. this dodgy concrete is in some hospitals, too.

ceilings popped up to keep them working. last year the health secretary repeated a promise to remove it. there are huge concerns about issues in terms of the raac concrete used in certain hospitals which needs urgent attention. for the affected schools, it is now a race against the start of term working out how to keep children learning and safe. branwen is here. why has all of this emerged just before the new academic year begins? that is a very good question, because we know that in 2018 a school roof collapsed in kent. no one was hurt, but that ruth had raac in it, the starkest of warnings of the potential risk to life or injury of children. by 2021 the department for education had rated the risk of a school building as failing as

being critical so they have known about this for some time and yet since then, despite the efforts that have been made to try and gather information from schools, we still don't know the full extent of it. but a very critical report from the national audit office early this year pointed out that not enough was being spent on school buildings, not enough was known and that appears to have galvanised action. find have galvanised action. and therefore — have galvanised action. and therefore tonight _ have galvanised action. and therefore tonight parents watching this who are wondering if their own child's school will be affected, what should they do? at child's school will be affected, what should they do?- child's school will be affected, what should they do? at the moment it's 'ust 156 what should they do? at the moment it's just 156 schools _ what should they do? at the moment it'sjust 156 schools out _ what should they do? at the moment it'sjust 156 schools out of— what should they do? at the moment it'sjust156 schools out of more - it's just 156 schools out of more than 22,000. if your school is affected the school will get in touch directly with parents. so if you haven't heard, it's good news. branwen, rank you very much, our education editor branwenjeffreys there. —— thank you very much. twelve children are among more than 70 people now known to have died after a fire in a five—storey block in south africa —

where it's thought a locked gate prevented people escaping the flames. it happened injohannesburg, where our correspondent shingai nyoka has been witnessing the aftermath. shejoins us now. she joins us now. that's right, and there is incredible sadness in the air tonight here. authorities are describing this fire as an unprecedented tragedy and earlier this evening president cyril ramaphosa visited the victims in the inner city ofjohannesburg to try to console some of the survivors in what has been an unimaginable day for so many families. and just a warning that some of their stories are disturbing. screaming. the sound of screaming piercing the night in the heart of africa's richest city. "fire! fire!" they shout from a burning building home to hundreds of people. officials say many residents were trapped inside by a gate, blocked by the bodies of those

who had already died. i was watching out of the window, all of the building was on fire so i decided myself tojump first. ijumped down, my wife throw for me the baby, i catch him. i tell her to tie a bed sheet. she tied a bed sheet and came down it. i catch him. relief and shock etched on the faces of those who managed to escape, but the rows of body bags are a grim reminder of those who didn't. many who lived inside this building were migrants from across the continent. the residents here were living in overcrowded conditions without consistent electricity or water. authorities say it resembled an informal settlement with shack—like partitions of cardboard boxes and sheets that likely fed the fire. now that the flames have been extinguished, the realisation that not everyone is coming out

has set in. translation: i couldn't get into the second floor- because the fire was so bad. someone found my five—year—old and rescued him buti lost my two—year—old. i don't know what to do, i don't know where to go. the flames were so intense that people inside have been said to be burnt beyond recognition. i have got about 23 years in the service, i have never come across something like this in my whole life. we sympathise with the people who have lost their lives, the residents who have lost their lives here, but we must do something about it as a city, working together to make sure we prevent incidents like this one. this evening, a visit by the south african president. support for him evident even among those grieving. the ministers and the mses and the province and the city are working now full out to make sure that those who need assistance

from accommodation to trauma counselling to hospitalisation are being looked after. while the cause of the fire is still unknown, authorities are promising a thorough investigation as loved ones in mourning demand answers about one of the worst fires in south africa's history. shingai nyoka, bbc news, johannesburg. junior doctors and consultants are to go on strike together in england, in an escalation of their pay dispute with the government. the coordinated action will begin towards the end of next month after an overwhelming union members' vote in favour. our health editor hugh pym is here with all the details. yes, mishal. nhs hospitals in england will see strike action byjunior doctors that started in the spring now continuing into the autumn. junior doctors will walk out on the 20th, 21st and 22nd of september, coordinating with strike action

with consultants that's already planned for the 19th and 20th. then bothjunior doctors and consultants will walk out again on the second, third and fourth of october if the dispute over pay hasn't been settled. emergency care will be covered. we've made it very clear that we'd be willing to talk at the drop of a hat without any preconditions at all, which unfortunately is at huge odds to what the government has been showing. it's now been more than 150 days or so since ministers have met with both us and our consultant colleagues, and itjust shows how clearly they don't value the profession or the public. junior doctors in england want a phased 35% pay rise to compensate for inflation over 15 years. the government says they'll get an average of 8.8%, a final offer and in line with the independent pay review body. consultants haven't said exactly what they want. so what does it mean for patients? tom, from wellingborough,

has a painful knee injury and was referred for treatment in may last year, but since then three appointments have been cancelled. whereas before it used to just be the occasional twinge, now it's literally a constant pain in the knee — nag, nag, nag. if i inadvertently catch, turning it the wrong way, i can't tell you how excruciating the pain is for several minutes. itjust shoots up the leg and takes my breath away. at least one appointment was postponed because of the junior doctors' strike. i think they're being a bit greedy. a massive pay rise doesn't seem to be justified in any way, shape or form. the first junior doctors' strike was in march. there have been 19 days of action in all, the most recent lasting for a full four days. the consultants have only walked out on four days so far, but this joint action will cause more of a headache for hospital managers.

with any industrial action, we've seen this since january, the impact is significant. i have no doubt with what's just been announced that a significant amount of elective care, if not all elective care, will be cancelled at our hospital during those periods of strike. in scotland, junior doctors have agreed a deal with the scottish government, with an increase of 12.4% this year. in wales, hospital doctors are set to ballot on further action. the health secretary in england urged the bma to end what he called the "callous and calculated" disruption. mishal. thanks very much. after studying nearly 2,000 patients admitted to hospital with the coronavirus, scientists believe they have identified why some people have experienced "brain fog" and fatigue as they suffered from long covid. our health correspondent cath burns is here to explain. what are they saying? they are

callin: what are they saying? they are calling this _ what are they saying? they are calling this a — what are they saying? they are calling this a significant - what are they saying? they are | calling this a significant advance and they say it's very exciting. the ultimate aim here is to find a treatment, to stop the symptoms of long covid, but it's hard to do that if you don't understand what is causing it and for a while now the idea has been that blood clots could be part of the explanation. now this team says they've got the first large—scale evidence of that. so what is that evidence? they found two proteins pointing to blood clots. the idea here is let's say someone had a covid infection and at the time they would have had a blood clot, may be in their brain or lungs. overtime clot, may be in their brain or lungs. over time that blood clot would have disappeared, but the damage it caused didn't go away and that's what went on to because, they think, these are symptoms of memory loss and problems with concentration. but then the question for us now is how does this understanding move things on? the good news here is we don't understand a lot about blood clots so remember that ultimate aim, finding a treatment —— the good news

is we do understand a lot about blood clots. for people who already have long covid, the aim would be to reverse some of that damage. if you are thinking of the intense brain rehabilitation that stroke patients have. then, because covid is still here, cases are low but rising, for the future the aim will be to prevent this case it's happening at all. there is a lot of work still to do but this is an important step. interesting, thank you very much. police in pakistan say they did not receive a formal request to start searching for the family of ten—year—old sara sharif until five days after her body was found in the uk. surrey police say they were talking to international partners from the day the body was discovered, which was after the child's father, stepmother and uncle are believed to have flown to islamabad. our pakistan correspondent, caroline davies, has been following the trail. more than 8,000 kilometres from woking, retracing the last known steps of sara's family.

what happened in their first days in pakistan? this is the small village that the police have told us they believe is the last place urfan sharif, beinash batool and faisal malik visited before they disappeared. we found their relatives. they didn't want to appear on camera. so, we were able to speak to the family but they didn't want to talk to us about what happened that evening. they neither confirmed nor denied that the family had visited, but what they did say is that urfan sharif�*s brother—in—law was taken several days ago by police and they haven't seen him since. neighbours didn't want to talk over, until, as we were about to leave, an uncle of mr sharif�*s brother—in—law. translation: yes, i urfan sharif visited us. i didn't meet him personally but my family told me in the morning that he came with his family at night. we are very worried about why the police took my nephew. if there is any issue with urfan�*s family, we have nothing to do with that.

domeli is close to this city, mr sharif�*s hometown othelum. several of his brothers were detained and questioned here. from islamabad airport, police believe relatives picked up the family, taking them to urfan sharif�*s brother's home in jhelum. on the 12th of august, they left late at night, stopping for a few hours at his sister's home in domeli, before leaving early on the 13th of august. on the 15th of august, pakistan police say they were asked through interpol to start the search. surrey police told us it had been liaising with international partners since the 10th but would not tell us when it submitted an interpol request. police remain optimistic they can still find the family. for them i think it would be very difficult to stay in hiding for quite some time. it's just like two weeks have passed, people will be giving information.

at the end, they will be contacting different people for different needs. we are working on it day and night so i'm sure that we will be able to find them. weeks on, still no sign of a family of eight in hiding somewhere in pakistan. caroline davies, bbc news, domeli. a new defence secretary has been appointed today, with grant shapps taking over, after ben wallace — who has done the job for the last four years — stood down. for grant shapps it's his fifth cabinetjob in the last 12 months, as our political editor chris mason reports. the wheels of politics are turning with a bit of zip again. before mps return next week, downing street has a spot of housekeeping to attend to, finding a new defence secretary. enter then grant shapps — the government's utility man has another newjob.

it is his fifth — yes, fifth — cabinetjob in a year. this then the first of many uniformed companions for grant shapps, as he left downing street and headed for the ministry of defence. what is your first priority? first of all i will get my feet in the door and pay tribute to my predecessor, i think. he is talking about this man, ben wallace, the former soldier turned defence secretary who had done the job for four years under three prime ministers. in his resignation letter he wrote: "i genuinely believe that over the next decade the world will get "more insecure and more unstable." he also said: "we must not return to the days where defence was viewed "as a discretionary spend by government and savings "were achieved by hollowing out." is grant shapps just going to be a political appointee, whose primary task if you like will be to support the prime minister in cabinet?

or is he going to really understand the needs of defence? grant shapps's replacement as energy secretary is claire coutinho, a long—standing ally of the prime minister. it is a huge promotion for her. are you ready to tackle the global energy crisis, miss coutinho? it really doesn't matter how many newjobs rishi sunak gives to his friends, it is still moving the deck chairs. they are still a sinking ship. this country really needs change. defence secretary is always a big job but claire coutinho faces the tricky business of delivering the government's climate promises with some tory mps sceptical about the implications. taking a step back, this was a safety first reshuffle. loyalty in the prime minister prized and, yes, limited in scale. chris mason, bbc news, at westminster. meanwhile, as the foreign secretary's visit to china takes place, there's new evidence of tension around long—standing territorial disputes

in the south china sea. officials in the philippines have told the bbc they will not be daunted by a chinese ship using water cannon against filipino coastguards approaching a contested reef. china has long claimed a considerable expanse of the sea as its own waters — the area within the red dotted line you can see here. that's in contrast to the internationally recognised system that you can see marked here in blue — assigning countries in the region waters 200 nautical miles out from their coast. in the centre of this part of the sea are the disputed spratly islands and our asia pacific correspondent laura bicker sent this report from near there — the island of palawan in the philippines. on the edge of this filipino paradise, survival depends on the sea. if you don't fish, you don't eat.

they are used to battling wind and tide, but this country is also in a stand—off with beijing over who owns which part of the south china sea. this crew used to fish near contested waters. from the age of 1a, the deputy captain spent months on those shoals but not any more. translation: we might not return there, ma'am. - we are now scared. we're scared of china. we were harassed and even asked to leave. the fishermen have been asked tojoin a militia to help defend filipino territory. but life is already bathed in saltwater and sweat while steering boats made of simple bamboo. they have no wish to take on a global superpower. translation: you feel guarded. how can we feed our families?

what we need is to fish, that's our goal, out in the sea. the chinese might fire their water cannons. we just have a wooden boat. we're really afraid of going back there. this is what the fishermen are afraid of. the chinese fired their water cannons at the filipino coastguard earlier this month. these are philippine waters according to un law. resolved to keep hold of their reefs, manila deliberately ran aground a rusting world war ii ship on what is known as ayungin shoal. but recent monthly efforts to supply troops on board with food and water have become increasingly tense. china argues that it is doing what is necessary to protect its sovereignty, its claims over the south china sea. the problem is that beijing's tactics and beijing's actions are pushing american allies in this region closer together, against what they see as aggression.

in a show of solidarity, australia held its first large—scale joint exercises with the philippines last week. they practised retaking an enemy—controlled island. and in manila bay, japanese and us navy warships sit side by side, ready forjoint drills. allied support has emboldened the philippines to speak out. really it is a david versus goliath issue, butjust like david, we will continue to pound and double down on the need to protect the resources which are important for the future of the philippines. the outcome of this dispute could have a profound impact here. where once their future was determined by ocean currents, now it may depend on the resolve of world leaders. laura bicker, bbc news, palawan.

the bbc has uncovered evidence that dozens of women were groomed into online sex work by members of a secretive all—male organisation called "the war room" — fronted by the influencer andrew tate. messages linked to the group show how members are taught — for a fee — how to exploit potential victims by emotionally manipulating and socially isolating them. mr tate denies any wrongdoing. here's the investigation, by matt shea. the war room is kind of like the illuminati but cooler. with brotherhood and people you can trust and capable people. that's what the war room is. andrew tate's so—called war room costs more than £6,000 a year tojoin. he describes it as a self—improvement and professional network. in reality, leaked messages reveal it teaches members through its so—called phd course how to groom women into sex work. our documentary has been given exclusive access to 12,000 pages of encrypted messages sent

by hundreds of its members. the encrypted messages identify at least 45 potential victims from around the world, with the true number likely much higher. a young woman from buenos aires says that she was groomed by a war room member. he bombshelled me with love, he wants me to get his name tattooed at all cost. and she says things even turned violent. drastic level of violence and submission that i never thought i will be involved with. another woman told me a similar story. he wanted me to tattoo his name on me. although they live thousands of miles apart, their stories indicate that their alleged groomers were following the same tactics. if i wasn't doing well, things would become more violent. there was a night that i had gone over there and as soon as i walked in the door he pushed me to my knees and smacked me really hard across the face. while andrew tate is the public face of the society,

our investigation has found that an american man named miles sonkin, who calls himself iggy semmelweis, appears to be its true leader. in documents and messages seen by the bbc, sonkin appears to encourage the members to remove the women's support systems, take all or most of the money they earn, and create, in his words, female sexual slavery. i also spoke to eli, who said he spent two years at the organisation as its head of sales and marketing, but has now left to speak out against it. iggy, he basically said, let's not kid ourselves, this is a cult. who's in charge? of the war room? iggy�*s at the top, yeah. i put these allegations to sonkin, at his home in los angeles. iggy semmelweis, are you training people in the war room how to enslave women? do you run the war room? we've seen chatroom evidence that you're training men how to enslave women. do you care to comment on that? he did not respond to me, but wrote

on social media afterwards. "i say nothing. "now matt will never know who the real mastermind of the war room is. matt bleep again." andrew tate has managed to appeal to the insecurities of millions of young men. our investigation suggests his fame is being used to sell a method of abuse to men around the world. a statement issued by mr tate's press officer said the bbc�*s findings represent another brazen attempt to present one—sided, unverified allegations against him. matt shea, bbc news. tennis — and there were no less than six britons playing in the second round of the us open today, where the action included a defeat for andy murray. joe wilson was kept busy watching it all. andy murray. all that andy murray's done deserved the biggest court. 23,000 seats — gradually occupied. now, he's been positive about his mobility.

could he possibly reach that? no way! huh! the opponents found themselves on the same side. bulgaria's grigor dimitrov took control. murray's frustration grew as the points and the games were lost. dimitrov is the seeded player and in straight sets he showed it. double fault to end, hard reality. now, here's a british serve. at 21, jack draper's already endured more injuries than he'd care to mention, so focus on his performance against the 17th seed hubert hurkacz. the polish player received some medical attention but he couldn't live with draper. straight sets win against one of the world's best. draper in dreamland. this reaction absolutely earned. five minutes laterjust across the courts, another british victory. that's katie boulter at the top of the screen against world number 114, wang yafan of china.

three sets to the third round for boulter. jodie burridge, in blue, won five games against aryna sabalenka, but the second seed was ultimately too strong. dan evans to come, cam norrie here in progress. it's like wimbledon in new york, in full colour! joe wilson, bbc news. time for a look at the weather. here's louise lear.
